I switched from a Salifert test kit to a new API master test kit and I'm noticing that the nitrAte reading is higher than I think it should be. Has anyone else noticed this?
Here's the test I tried. I compared:
The spring and tap water did not look yellow. They were light orange and the tank water was a darker orange. So from this I am presuming that the test is off by 10 or 15 ppm.
Would anyone like to comment on this experiment and/or the results or share similar experiences?

Here's the test I tried. I compared:
- tank water
- tap water
- bottled spring water
- The kit has not expired.
- I do the required shaking of bottle #2 and the final vial. The tank is a lightly planted 30 gallon well stocked with fish.
- Tap water report showed no nitrAtes. (lab tested)
- Assuming bottle water doesn't have nitrAtes.
